How to code a working Pie Menu for Sequencer?
Too many shortcuts in keymap def.


Define the space for keymap
Use keyword arguments to make sure they are assigned correctly.


edit:

wm = bpy.context.window_manager
km = wm.keyconfigs.addon.keymaps.new(name="Sequencer",
         space_type='SEQUENCE_EDITOR')
kmi = km.keymap_items.new("wm.call_menu_pie", 
        type="S", 
        value="PRESS")
kmi.properties.name = "pie.vsetools"
